UNITED STATES CHARLES N. CARLSON, OF VIRGINIA, MINNESOTA.

STORM-SASH FASTENER.

Application filed October 28, 1926. Serial No. 144,782,

This invention relates to storm sash fasteners and relates particularlyto that type of fastener' which operates simultaneously with themovement of the lower sash of the window to which the storm sash isapplied.

The principal object of my present invention resides in the provision ofmeans operable in conjunction with the fastener for more positivelyholding the storm sash tightly against the abutments of the window framewhen closed.

Another object is to provide simple means for limit-ing the upwardmovement of the sash of the window by which theV storm sash fastener isoperated.

Other objects and advantages of the invention will appear in the furtherdescription thereof.

Referring now to the accompanying drawing, formingl part of thisapplication, and wherein like reference characters indicate like parts:

Figure 1 is a perspective view of a fragmental portion of a storm sashand window` frame illustrating their open cooperative relationresulting` from the attachment of my improved fastener; and

Figure 2 is a broken side elevation of the window frame and storm sashin its closed position.

1 represents the inner face of one side of a common window frameprovided with the common inner and outer stops 2 and 3 respectively.and, in dotted lines7 as at 4` is represented the lower sash of thewindow as mounted within the frame 1 and susceptible of verticaladjustment as is common.

5 represents the lower fragmental portion of ay common storm sash, and 6is the fastener arm which is pivotally connected as at 7 to the bracketSupon one edge of the storm sash, and at its opposite end as at 9 to thebracket 10 which is securely fixed as by suitable screws or the like tothe sash 4; the fastener arm here illustrated is preferably of thedesign shown in my former Patent No. 1,607,944 differing however in thatat the window sash end it is provided with a depending stop member 11,secured as by lsuitable rivets indicated at 12 adjacent the pivotalpoint of said arm, the stop member of the arm 6, so that when the windowsash 4 is raised to a position which will bring the arm 6 substantiallylparallel with the squared end of the stop 11 it will abut against theface of the bracket 10 and thus stop the upward movement of the sash,as-

suring against disarrangement of the auXiliary4 attachment t`o thefastener hereinafter described, as well as insuring the proper relationbetween the window sash and the storm sash at all times.

The auxiliary attachment connected with the fastener arm consists of theflexible cord, rope, or wire, as the case may be, indicated at 13, whichis provided with a suitable eye 14 at either end thereof, said eyesbeing designed to encircle the pivotal support at either endintermediate of the arm and brackets to which the latter are attached.the Wire being payed through the screw eye 15 fastened within the stop 2spaced somewhat above the uppermost travel of the window sash 4 aslimited by the stop heretofore described upon the innermost end of thefastener arm. This wire is of the proper length v to permit offunctioning as disclosed in the drawings, and holding` the storm sashtightly against the stop 3 when the window sash is 1n closed position,thus providing a direct pull on the wire intermediate of the screw eye15 and the pivotal point 7 As is obvious the stress upon the wire whenthe window is closed may be governed bythe length thereof as well as bythe position of the eye 15, and the eye may be of somewhat differentconstruction and provided with a roller if desired, as its specificshape does not form part of my present invention other than that thehole therein must be suiliciently large to permit of either eye 14freely passing therethrough to allow the same to be readily installed. c

Having thus described my invention, what I claim and desire to secure byLetters Patent, is: v f

l. The combination with a storm sash fastener attached at one end to astorm sash and at the opposite end to a window sash, of a limiting stopattached to said fastener, fiexiblemeans attached at one end to the loostorm sash and at the other e'nd to the winv flexible means is payed sopositioned as to prevent damaging engagement of the fastener armtherewith.

p 2. 1n combination, a storm sash fastener 5 attached at one end to astorm sash and at the opposite end to a Window sash, a iexible l cordhaving its ends attached to the ends of CHARLES N. CARLSON.
